“Multivitaminsndiwo anonyanya kuzivikanwa ezvekudya, anogara achitorwa neanenge chikamu chimwe muzvitatu chevakuru vekuUS.Basa rechinyakare remazuva ese multivitamin kudzivirira kushomeka kwekudya.Iko kusanganiswa kwemavhitamini akakosha nemaminerari ari mumultivitamin anogona kuratidza hutano hwekudya hwakadai semichero nemiriwo yekudya, izvo zvave zvine mwero uye zvinopesana nenjodzi yegomarara mune zvimwe, asi kwete zvese, epidemiologic zvidzidzo.Observational zvidzidzo zvenguva refu multivitamin kushandiswa uye kenza kupera pfungwa kwave kusingaenderani.Parizvino, miyedzo mikuru-yakakura yekuyedza imwe kana diki nhamba yemhando yepamusoro yevhitamini uye zvicherwa zvegomarara zvakawanzowana kushomeka, "akadaro mumashure ruzivo mujenari."Zvisinei nekushaikwa kwechokwadi chekuyedza data maererano nemabhenefiti emultivitaminsmukudzivirira zvirwere zvisingaperi, kusanganisira kenza, varume nevakadzi vakawanda vanozvitora nokuda kwechikonzero ichi chaizvo.”
J. Michael Gaziano, MD, MPH, weBrigham and Women’s Hospital uye Harvard Medical School, Boston, (uyewo Contributing Editor,JAMA), uye vaaishanda navo vakaongorora data kubva kuChidzidzo cheVanachiremba 'Health Study (PHS) II, iyo chete yakakura-yakakura, yakasarudzika, yakapetwa kaviri-mapofu, placebo-inodzorwa yekuyedza mhedzisiro yenguva refu yeakajairika multivitamin mukudzivirira chirwere chisingaperi.Kuedza uku kwakakoka 14,641 varume veUS varapi vakura kupfuura makore makumi mashanu, kusanganisira varume 1,312 vane cancer panhoroondo yavo yekurapa.Vakanga vakanyoreswa mune zvidzidzo zvevhitamini zvakatanga muna 1997 nekurapa uye kutevera kusvika munaJune 1, 2011. Vatori vechikamu vakagamuchira multivitamin zuva nezuva kana kuti yakaenzana placebo.Mhedzisiro yakayerwa yechidzidzo yaive gomarara rakazara (kusanganisa gomarara reganda renonmelanoma), ine prostate, colorectal, uye mamwe saiti-chaiwo kenza pakati pechipiri yekupedzisira nzvimbo.
PHS II vatori vechikamu vakateverwa kweavhareji yemakore 11.2.Panguva yekurapa mavhitamini akawanda, paive ne2,669 dzakasimbiswa dzegomarara, kusanganisira 1,373 zviitiko zvegomarara reprostate uye mazana maviri negumi egomarara remukati, vamwe varume vachisangana nezviitiko zvakawanda.Huwandu hwevarume ve2,757 (18.8 muzana) vakafa panguva yekutevera, kusanganisira 859 (5.9 muzana) nekuda kwekenza.Ongororo yedata yakaratidza kuti varume vanotora multivitamin vane mwero 8 muzana kuderedzwa kwekenza yakazara chiitiko.Varume vanotora multivitamin vaive nekuderedza kwakafanana kwekenza yesero epithelial.Inenge hafu yezviitiko zvese zvegomarara yaive kenza yeprostate, mazhinji acho aive ekutanga.Vatsvagiri havana kuwana mhedzisiro yemultivitamin pagomarara reprostate, nepo multivitamin yakaderedza zvakanyanya njodzi yekenza yakazara kusasanganisa kenza yeprostate.Pakanga pasina kuderedzwa kwakakosha kwekenza mune yega saiti-chaiyo kenza, kusanganisira colorectal, yemapapu, uye dundira, kana mukufa kwegomarara.
Kushandiswa kwezuva nezuva kwemultivitamin kwaibatanidzwawo kwaive kuderedzwa kwekenza yakazara pakati pevarume 1,312 vane nhoroondo yekutanga yegomarara, asi mhedzisiro iyi haina kusiyana zvakanyanya kubva kune yakaonekwa pakati pevarume 13,329 pakutanga vasina cancer.
Vatsvagiri vanocherekedza kuti huwandu hwegomarara mukuyedzwa kwavo hunogona kunge hwakapesvedzerwa nekuwedzera kwekutarisa kweprostate-specific antigen (PSA) uye kwakatevera kuongororwa kwegomarara reprostate panguva yekutevera kwePHS II kutanga mukupera kwema1990."Inenge hafu yekenza dzakasimbiswa muPHS II yaive kenza yeprostate, iyo ruzhinji rwacho rwakanga rwuri danho rekutanga, regiredhi rezasi gomarara reprostate rine huwandu hwekupona.Kudzikiswa kwakakosha kwekenza yekenza minus yeprostate kunoratidza kuti kushandisa mavhitamini ezuva nezuva kunogona kuve nerubatsiro rwakakura pane zvakanyanya kuongororwa kenza.
Vanyori vanowedzera kuti kunyangwe akawanda mavhitamini nemaminerari ari muPHS II multivitamin kudzidza akatumira chemopreventive mabasa, zvakaoma kunyatsoona chero nzira imwe chete yemhedzisiro kuburikidza iyo munhu kana akawanda zvikamu zveyavo yakaedzwa multivitamin ingave yakaderedza njodzi yegomarara."Kudzikiswa kwenjodzi yegomarara muPHS II inopokana kuti kusanganiswa kwakawanda kwemavhitamini akaderera-dosi uye zvicherwa zviri muPHS II multivitamin, panzvimbo yekusimbisa kune yakamboedzwa mavhitamini epamusoro-dose nemamineral miedzo, inogona kuve yakakosha mukudzivirira cancer. .…
